Cancer-related fatigue (CRF) is commonly reported by patients both during and after receiving treatment for cancer. Current CRF diagnoses rely on self-report questionnaires which are subject to report and recall biases. Objective measurements using a handheld dynamometer, or handgrip device, have been shown in recent studies to correlate significantly with subjective self-reported fatigue scores. However, variations of both the handgrip fatigue test and fatigue index calculations exist in the literature. The lack of standardized methods limits the utilization of the handgrip fatigue test in the clinical and research settings. In this study, we provide detailed methods for administering the physical fatigue test and calculating the fatigue index. These methods should supplement existing self-reported fatigue questionnaires and help clinicians assess fatigue symptom severity in an objective and quantitative manner.
癌症相关疲劳（CRF）在癌症患者接受治疗期间及之后都很常见。目前CRF的诊断依赖于自我报告问卷，而这些问卷容易受到报告和回忆偏差的影响。最近的研究表明，使用手持测力计或握力装置进行的客观测量与主观自我报告的疲劳评分显著相关。然而，握力疲劳测试和疲劳指数计算在文献中都存在差异。缺乏标准化方法限制了握力疲劳测试在临床和研究环境中的应用。在本研究中，我们提供了进行身体疲劳测试和计算疲劳指数的详细方法。这些方法应补充现有的自我报告疲劳问卷，并帮助临床医生以客观和定量的方式评估疲劳症状的严重程度。
